VALVE.

Specification of Letters Patent.

Application led September 26, 1918. p Serial No. 255,868.

To ZZ whom it may concer/a.'

Be it known that ANDREW J. ENeLrsH, a citizen of the United States, residing at the city of Cincinnati, in the countyA of Hamilton and State of Ohio, has invented certain new and useful Improvements 1n Valves, of which the following is a specification.

The object of my invention is to provide a valve or valve seat which will expand or contract under use to which it is subjected, so as to be self compensating and thus always be of the proper diameter and contig vuration needed during the operation oit the parts acting in conjunction therewith. It will also take up the wear ot the parts and thus always 'present desired .operative form. In carrying out my invention I provide a yielding or flexible valve seat as hereinafter set forth.

In the accompanying drawing, forming part of this specilication:

Fig. l, is a plan view taken on line l-l of Fig. 2;

F 2, is a sectional view taken on the line 2--2 ot Fig. I;

Fig. 3, is a plan of the valve seat partly broken away to show the spring;

Fig. 4, is a sectional view on line 4 4 of Fig. 3, and

Fig'.l 5, is a sectional view of the valve seat and connecting parts, the valve shown in elevation, and being flat, for use with an air controlled apparatus or pump.

In Figs. l, 2, 3 and 4, I illustrate the invention as applied toagftoilet flush tank.

In the drawings,` the flush tank is marked Yl and at its bottom I provide the usual outlet pipe 2, of any suitable form, and provide at its inner extremitya holding flange 13. I provide float valve 5, preferably Yformed as shown, however, any form may be used which is found desirable. I provide a. usual iorm of plunger 6 suitably supported in the tank l and connect a lever 7 between it and the float valve 5, by means of which it is .raised oil2 its seat and as the water recedes in tank l, the suction draws the valve 5 back down upon its seat.

The float valve seats on a flexible, yielding and compensating valve sea-t, which is the main feature of my invention.

I will'describe one form of making and using the same in connection with a flush tank apparatus or device. The valve seat is preferably circular, annular or like a ring 1n shape, but may be made of any form or shape found desirable in practice. In the present instance the valve seat is formed of a coiled spring 8, forming a ring like configuration, a. ileXible covering 9 encompassing said coiled spring; this flexible covering is looped over said spring and its ends or edges are connected together by screw and flange connections 10 or in any suitable manner. The looped part is full and extendsout somewhat from the spring to give play to the spring when it expands or contracts and this looped part ismarked 12.

This valve seat is placed loosely on top of the flange 13 of outlet pipe 2. The float valve 5 is always seated on the seat formed of ring 8 and flexible covering 9 as shown in solid lines in Fig. 2, and when the plunger 6 and lever 7 are operated the valve 5 leaves its seat as shown in dotted lines. IVhen the valve 5 is down it is tightly seated and when elevated remains up Vuntil the water recedes and when it has receded to a certain line the suction created in the flushing tank pulls the valve 5 down onto the seat, and when seated, the valve seat again impinges sufciently against valve 5 to hold it on the seat, thus the eXpansion and contraction of the spring like ringis self compensating to always form a proper seat for the valve.

In the tank l, I show an overflow pipe 3() connecting with a by-pass 3l, so that if the inlet valve should leak, the water will overflow through pipe 30 and by-pass 3l out through pipe 2. All these parts and those which form the valve seat and connections can be loosened up by loosening up flange 13 and turned through an arc of 180 degrees and when this is done the plunger 6 will pass through hole 32 in the other side of the tank l.

The inlet valve and connections and other parts are not shown herein, as they are not `part of this invention.

In Fig. 5, I show the valve seat in connection with a flat faced valve 40; this construction being suitable for use in connection with air operated valve mechanism. In this Fig. 7, the valve 40 is shown o of the valve Patented Aug. 2e, i922. f

of carrying my invention into effect, it will be obvious that the same may be modified to some extent and I wish to be understood as claiming` that such modications will still fall within the scope of my invention.

Vvhat I claim as new and my invention and desire to secure by Letters Patent 1s:

A Valve seat formed of a one piece coiled ySpring in annular shape and capable of exl5 panding and contracting, combined with a vflexible material enveloping the same and extending materially outward therefrom to allow play for the spring.

In testimony whereof I aflix my signature. 20
